To find the total number of sit-ups Ishaan did, we can multiply the number of sit-ups he did each day (148) by the number of days he did sit-ups for (29).

148 x 29 = <<148*29=4292>>4292

Ishaan did a total of 4292 sit-ups in those 29 days. Answer: \boxed{4292}.

To find the total number of sit-ups Ishaan did in those 29 days, you simply need to multiply the number of sit-ups he did each day (148) by the number of days (29).

148 sit-ups/day * 29 days = 4292 sit-ups in total
